On Wednesday, October 5th, several unions turned out in support of the Occupy Wall Street movement in a collective march. Protestors were joined by the Communication Workers of America, the Transport Workers Union Local 100, the United Federation of Teachers, and 2 SEIU chapters. Nearly 15000 turned out for the march which brought lower Manhattan to a near standstill. As the march continued into the night, the NYPD response got more aggressive, with repeated baton-assaults, pepper-macing, and arrests. Nearly two dozen were arrested that night.

This was the third time Occupy protestors clashed with the police, and the number of arrests now totalled over 800. This was the third consecutive clash with police in New York over the Occupy movement.
